如何实现 C#winform ListView 鼠标移入行时，行变色高亮

Answer 1

ItemMouseHover事件
e.Item获取项 然后在做处理

或者用DrawItem事件吧
private void listView1_DrawItem(object sender, DrawListViewItemEventArgs e)
{
if(e.State == ListViewItemStates.Hot)
{
Pen blackPen = new Pen(Color.FromArgb(255, 0, 0, 0), 5);
e.Graphics.DrawRectangle(blackPen, e.Item.Bounds);
}

}
